 Title    Darstellung und Kristallstruktur von Antimon(V)oxidhydroxid HSb308 Preparation and Crystal Structure of the Antimony(V) Oxide Hydroxide HSb30g  
 Abstract    Colourless crystals of HSb3Os were prepared by hydrothermal methods from Sb205. The crystal structure [P2/n, a = 945.6(2), b = 869.1(2), c = 990.9(2) pm, ß = 90.25(2)°, Z = 6. R = 0.045] was determined from diffractometer measurements. Distorted SbOe octahedra are linked through vertices and edges to form a three-dimensional polymer of pseudo-orthorhombic symmetry. The hydrogen atoms could not be located.

 Title    Quaternary Selenidogermanates(IV) A3[AgGe4Se10]*2H2O and A2[MnGe4Se10]*3H2O (A = Rb, Cs) with Open Framework Structures  
 Abstract    Hydrothermal reaction of Ge and Se with Ag(CH3COO) in the presence of alkali metal carbonates affords the open framework selenidogermanates(IV) A^fAgGejSeiol ^H^O (A = Rb, Cs), 1 and 2, which contain corner linked adamantane-like Ge4Seio cages and AgSe4 tetrahedra. The analogous reaction with Mn(CHiCOO)2 yields the isostructural tetragonal compounds A2[MnGe4Seio]-3 H2 0 (A = Rb, Cs), 3 and 4. The cations are sited at a general position in the channels of the silver bridged anionic framework of 1 and 2 and exhibit a disordered pattern of occupation (s.o.f. = 0.75) with one of the two crystallographically independent water oxygen atoms 0 (2) (s.o.f. = 0.25). In contrast, the Rb+ cations in 3 are disordered over all three cation/oxygen sites, and the cation/water occupation pattern is fully reversed for the larger Cs+ cations in 4 in comparison to 1 and 2.
